The Dragon Spacecraft Qualification Unit was a boilerplate version of the Dragon spacecraft. After using it for ground tests to rate Dragon's shape and mass in various tests, SpaceX launched it into low Earth orbit on the maiden flight of the Falcon 9 rocket. SpaceX used the launch to evaluate the aerodynamic conditions on the spacecraft and performance of the carrier rocket in a real-world launch scenario, ahead of Dragon flights for NASA under the Commercial Orbital Transportation Services program.
